You Tube page - Assembly and informational videos (MAY SHOW OLDER VERSION SO JUST USE AS REFERENCE ) https://www.youtube.com/channel/UCGIkWMOJv5XKnaVq2GG9P9g

Comes in Kit form assembly required - See You tube video on assembly (See our You Tube link on our home page )
Note : No rims nor Tire not included, no body. Our vision for this was since lexan is easy to form with hair dryer we would offer lexan sheets so with some creativity everyone will have a different bike look.Their maybe other aftermarket motorcycle formed bodies available you can cut or trim to fit. or you could use your imagination and cut and trim sections off other car bodies like our customers have which came out awesome.

Required to complete and important info :
Motor  - 2.5T and up   Current record ET 1.82 @ 77mph on a 2.5T fantom and 1s battery.
Some Motor shafts you will need to file or dremel flat spot on shaft longer towards the motor bearing so to get proper pulley belt alignment. You may also use motor Spacers behind motor and carbon fiber frame rail will also bring motor out for either balancing or pulley alignment.
2.5T or 3.0T or higher turn combined with 1s battery is what its designed for to fit.
Servo arms (Best to get cross type ARM and cut off 2 arms for dbl straight arm. Steering can be done many ways their is no wrong or right. suggested use 1/8" steel rod (found at any hobby store, 1/8" steel collars x4 ,3mm ball studs x2, 3mm ball cups x 2. Attach 1/8" rod with ball cups as 1/8" rod and 1 side threaded. Than place rod attached to servo arm through rod ends that come with kit, use 1/8 collars in front and back of rod end on rod to adjust and lock into place.

NOTE : When running belt drive be sure to check motor direction. Depending on which side you choose to have it on ( Normal direction is having belt on left side when looking at bike from rear) If you need to Reverse the motor direction that can be done by esc setting or radio, check radio and esc manual before doing operating.Most motors is recommend to set timing to "0" if running in reverse as when reversing direction turns + timing into - visa ,versa

Battery 1s  or 2s thin shorty- Recommend Fantom Racing ( we have available 2s thin which fit also )
1s - 6000mAH 149 grams - 7800 mAH  156 grams

Rear Foam Tire and Rim - 
Size Recommend is 2.75"T x 1.75" wide or 2.75 x 2" wide  which can fit a 2" wide but needs about 1/16" trimmed off both sides so dosnt rub. Best to use tire truer to do truing and trimming of widths. TM rc racing x compound  http://tmrcracing.com/1-10th-Scale_c26.htm  or BSR pink compound at Your Battery Buddy at www.yourbatterybuddy.com/index.php/wheels-and-tires/foam-wheels-tire/bsr-racing-foam-tires-wheels/bsr-1-10-scale-tires/bsr-1-10-foam-tires-and-wheels-pink-duro-30-35-1-75-x-2-75-1-10-scale.html
Gone Bananas racing skinz to name a few. You can true your heights lower as needed to dial in your ET and MPH also 6ft times better.

ESC - 
Recommended - Tekin RS Pro Black edition but you will need to run a receiver pack with it. The 1s version tekin dosnt need a receiver pack. If running the tekin esc you have a place under chassis to mount the Hotwire 3.0 bluetooth so youll never have to connect to program.
Hobby Wing XeRun XR10 PRO 1S
Castle mamba max 1s.
Be sure to check esc size and specs that manufacture supports 2.5T motors we know tekin does. Check with us first if your unsure of sizing if your esc fits.

Receiver Battery specs -  400-430  ish in mAH is about largest capacity pack that can fit.
Max Amps 430mAH 2s battery $19.99 www.maxamps.com/lipo-430-2s-7-4v-battery-pack its sizing fits perfect but check your receiver and servo used to make sure its rated for 7.4v prior. Sizing under bike for receiver to mount Max area for receiver battery- 50mm L x 30mm W x 18mm H

Servo  - Micro
Savox micro servo 21T Spline 6.6v SH-0265MG digital Dimensions: L 22.8 x W12 x H27.5 mm
MKS93i hv handles 6.6v,7.4v or 8.4v Dimension: 23x12x27.25 mm . Be sure to match your voltage which ever combo you use in servo,receiver and receiver battery. These are just suggestions.
Or any other micro servo with same or slightly smaller sizing.Some servos have single mounting hole others have 2 so pay attention when selecting or user will need to drill new hole location for servo.Spacing is tight so has to be real close in size and depth.
You can always use spacers under screw tabs to raise servo up to clear battery below if its taller.
Servo mount opening dimensions : 23.875mm Long (front to back viewing) 12.967mm wide (side to side) mount hole center to center distance 28.905mm .Servo mount opening can be filed to adjust do small amount at a time.
,
Foam tire Traction Compound -
Koford traction Med or heavy compound depending on track conditions. (Best to have both on hand)


Suggestion of extra parts to keep stock of and tip -
 Triple tree plastic mount blocks , servo saver dbl 21t arms here is link to a aluminum dbl arm www.towerhobbies.com/cgi-bin/wti0001p?&I=LXVPC3&P=7 , belts, front rim , spacers , rear bearings , ball cups and aluminum ball stubs , handle bar to name a few and shims.If you blow a rear axle bearing you can upgrade to 1/2" dia axle bearing but will require you to use step drill bit with largest dia less than 1/2" for tight press fit.

Comes with rear wheel clamp hub and axle,spacers etc.

Note: this is a A to B Drag bike for smooth clean surface roads of either prepped or non prep drag tracks or street. You must slow way down to turn around. Concrete is best surface unless you find a good asphalt surface. koford foam tire traction heavy compound will give best results on no prep.
When pressing in rear axle bearings onto carbon fiber rails on assembly dont force it tap in evenly.Most times it will snap in place.

Please note Kits require cnc machining so please allow few days or so for G10 Satin Black before they ship as their machined to order and all depends on cnc work load going on (Sometimes sooner) also allow 1-2 wks if carbon is ordered and is in stock for carbon fiber version before ships.
